new and useful Improvements in Ships Telegraphs, of which the followingis a specification.

`Uur invention relates to a telegraph of. `that type in Lwhich apredetermined Xed series of intelligences may be transmitted from onepoint to another on shipboard, andy more particularly to one of thosesystemsin l which use is made of step by step devices for transmittingandr receiving signals. It is particularly adapted for use kon shipboardand will be describedk as used thereon.y

While of the particular relation and adaptation vstated however, ourinvention may readily be used in part or as a whole in connection withother systems, and in other situations. r .Y f

The transmitter' of our invention is intended for use intransmittingsignals from the bridges of vessels to the engine rooms andreturn. Heretofore telegraphs have been used for this purpose which haveproven verysatisfactory as long as the apparatus was in order.Breakdowns due to one cause or another are not uncommon however, anduntil the apparatus is repaired great inconvenience results, andaccidents due to these causes are not unknown.

The object of our invention is to avoid these inconveniences, andliability to accidents, and to produce a transmitter which will bereliable under practically all conditions of service.

In the accomplishment of our invention connect one system from the otherand thereo Specification of Letters Patent.

by ignore the the signals. e r

The further aim of our invention is to construct a transmitter `so as byreducing the number of vseparate parts there are relatively fewoperativeparts `whereby to produce a simple structure which may beeconomically manufactured and willl occupy but very little space.

The above and other objects of this invention may be accomplished ybythe structure hereinafter described in detail and shown in theaccompanying drawings wherein, i Figure l is a front elevation vofthetranslnitter. F ig. 2 is a section on line 3 3 .of Fig. l. Fig. 3 isa front elevation withthe cover removed.

The numeral 18 designates a boX or casing, cylindrical in this instance.The particular transmitter shown is adapted to signal speed changes4from the bridge to anring 22 of insulating material carrying on itsinterior face two series of contacts 23, and 24, and between them acontact ring 25. Each of the contact members in the series of contacts23 and 2li is adapted tov be separately connected to respectiveelectrical indicators at the receiving station, while the contact ring25 is connected to a common return wire of the electrical system. Theconnection with the mechanical system is made from the pulley 2l of thetransmitter by a chain or belt passing around said pulley, as is usualin mechanical signaling means. Secured to the adjacent side of thepulley 21 is a block 26 of conducting material carryngthree Contactlingers 27 vyieldingly pressed into contact with the respective contacts23, 24e and 25, and adapted to complete electrical circuits from thecentral ring contact to the series of contacts on either side of it.Also journaledy in the casing yof the transmitter is a second shaft 28fixed in proof the same taken longation of shaft 20 and freely movablewith respect thereto, having its adjacent end loosely journaled in thesleeve 29 on the shaft 20 and its other end journaled in the front ofthe casing. This shaft carries a pulley 30 of the same formas pulley 21inside of the casing while on its other end it carries a pointer 31adapted to move over the dial of the transmitter. A chain or belt 35 isadapted to be received by said pulley 30 whereby the same may be rotatedfrom a receiving station so that the signal or order may be repeatedback to the transmitter' and indicated on the dial by the pointer 3l toshow that it has been properly received. An operating handle 32 isconnected to the end of the shaft 20 at the rear of the casing, and isprovided with a pointer 33 which overhangs the front of the casing andthe dial. When the pointer 33, by means of the handle 32, is moved fromthe stop indication to a position pointing to another indication on thedial, which latter indication is desired to be transmitted, both theelectrical andmechanical transmitting means are actuated simultaneously.Should one system become disabled the other one would transmituninterruptedly, and as pointed out, it is obligatory' upon the operatorthat he actuate both of the transmitting systems so that he cannotnegligently or wilfully rely upon only one of the systems and disregardthe other.

Vhat wewclaim is:

l. In an apparatus of the class described the combination of mechanicaltransmitting signal means having ya chain, an electrical transmittingysignal means having a plurality of fixed independent electrical contactterminals, and a fixed common terminal,

copies of this patent may be obtained for of a shaft, a pulley keyed onsaid shaft adapted to receive said chain whereby to actuate saidmechanical transmitting means, a plurality of contact `fingers mountedon said pulley and rotatable therewith and cularly arranged, a shaft insaid casing, a

handle on said shaft for turning the same, a pulley in said casing keyedto said shaft for the reception of said chain to actuate the same, and aplurality of contact fingers mounted on said pulley to turn therewithand adapted forV engagement with said terminals, one of said fingersbeing adapted for engagement with said common terminals.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
